Methods and systems for providing content are disclosed. Specifically, a content provider can transmit a plurality of content items to a plurality of user devices, and the plurality of content items can be synchronized at the one or more user devices. The plurality of content items can comprise one or more audio content items and one or more video content items ingested from a multimedia content stream. The disclosed methods and systems can be used in delivery of video descriptions, multiple languages, different types of narration such as director commentary, actor commentary, and the like.

An example method can comprise a first device receiving a first content item such as a video content item. The first content item can comprise a plurality of fragment identifiers. A plurality of second content items such as audio content items can be generated based on the first content item. Metadata associated with the respective plurality of second content items can be generated. The first content item can be transmitted to a first device via a first communication link. At least one of the plurality of second content items and the metadata associated with the at least one of the plurality of second content items can be transmitted to a second device via a second communication link.

The system 100 can comprise a central location 101 (e.g., a headend), which can receive content (e.g., data, input programming, and the like) from multiple sources. The central location 101 can combine the content from the various sources and can distribute the content to user (e.g., subscriber) locations (e.g., location 119) via distribution system 116. In an aspect, central location 101 can provide video content, audio content, or other content (e.g., text content, metadata, application) to a plurality of devices (e.g., a first device, a second device) at a specific location (e.g., location 119) or a multitude of user locations. For example, the central location 101 can comprise a first content provider configured to provide a first content item (e.g., video, audio, metadata, text, application) to a first device 122 a at location 119. The central location 101 can comprise a second content provider configured to provide second content items (e.g., audio content ingested from the first content item) to the second device 122 b at location 119. The first content item and the second content item can be synchronized at the central location 101 or at location 119.

In an aspect, the second device 122 b can comprise a synchronization element (e.g., synchronization element 123). For example, the synchronization element 123 can receive and process at least one of the plurality of fragment identifiers associated with the first content provided and/or render at the first device 122 a, and identify a corresponding location in the second content item. For example, upon receiving the at least one fragment identifier at the second device 122 b, the synchronization element 123 associated with the second device 122 b can access the metadata of the second content item to identify a location that corresponds to the received at least one of the plurality of fragment identifiers associated with the first content item. For example, the metadata can comprise a time index and corresponding fragment identifiers associated with the first content item. The location can be identified as a time offset (e.g., 15 minutes 9 seconds) with respect to the beginning of the second content item.

In an aspect, the central location 101 can receive content from a variety of sources 102 a, 102 b, 102 c. The content can be transmitted from the source to the central location 101 via a variety of transmission paths, including wireless (e.g. satellite paths 103 a, 103 b) and terrestrial path 104. The central location 101 can also receive content from a direct feed source 106 via a direct line 105. Other input sources can comprise capture devices such as a video camera 109 or a server 110. The signals provided by the content sources can include a single content item or a multiplex that includes several content items.

The central location 101 can comprise one or a plurality of receivers 111 a, 111 b, 111 c, 111 d that are each associated with an input source. For example, MPEG encoders such as encoder 112, are included for encoding local content or a video camera 109 feed. A switch 113 can provide access to server 110, which can be a Pay-Per-View server, a data server, an internet router, a network system, a phone system, and the like. Some signals may require additional processing, such as signal multiplexing, prior to being modulated. Such multiplexing can be performed by multiplexer (mux) 114.

The central location 101 can comprise one or a plurality of modulators 115 for interfacing to the distribution system 116. The modulators can convert the received content into a modulated output signal suitable for transmission over the distribution system 116. The output signals from the modulators can be combined, using equipment such as a combiner 117, for input into the distribution system 116.

A control system 118 can permit a system operator to control and monitor the functions and performance of system 100. The control system 118 can interface, monitor, and/or control a variety of functions, including, but not limited to, the channel lineup for the television system, billing for each user, conditional access for content distributed to users, and the like. The control system 118 can provide input to the modulators for setting operating parameters, such as system specific MPEG table packet organization or conditional access information. The control system 118 can be located at the central location 101 or at a remote location.

The distribution system 116 can distribute signals from the central location 101 to user locations, such as user location 119.

In an aspect, a plurality of second content items can be generated (e.g., ingested) based on the first content item. For example, the plurality of second content items can be a plurality of audio files ingested from the first content item. Examples of audio content items can be audio files generated for hearing aids (e.g., loudness), multiple language options (e.g., English, Spanish, French), parental control (e.g., certain words removed), narration, video description (e.g. for blind people), director's commentary, music-only versions, parody dialogs, minors' versions (e.g., no music or effect), 3-D audio (e.g. object based audio), and/or the like. The plurality of second content items can be in a plurality of formats such as MP3, AAC, MID, AIFF, WAV, MOV, M4A, MP4, and/or the like. In an aspect, loudness can be shaped on a server side or a client side of a content distribution network.

In an aspect, the first content item and each of the plurality of second content items (e.g., audio files) can be associated with metadata to describe the respective content items. For example, the metadata can comprise descriptions of the respective audio files, such as hearing aids (e.g., loudness), language training (e.g., English, French, Spanish), parental control, narration, music-only versions, minors' versions, 3-D audios, audio formats (e.g., mp3, mp4, wav, mid, etc.), and/or the like. A menu can be created based on the metadata of the plurality of second content items. In another aspect, metadata can comprise a time index and corresponding fragment identifiers. As an example, the time index can indicate a time offset with respect to the beginning of the respective second content item. In an aspect, the time index can comprise a time offset value from the beginning or a specific segment (e.g., packet) of the respective second content. In an aspect, the time index can comprise a corresponding packet number of the respective second content. In another aspect, the time index can comprise clock/time information carried in a program or a transport stream as a universal time reference. For example, every object (e.g., main content, advertisement) in a content item can carry timing metadata. For fragmented videos, fragment identifiers can be used as time index. In this scenario, a callback from the second device can be used to synchronize the first content item provided and/or rendered at the first device (e.g., television) and the second content item provided and/or rendered at the second device (e.g., tablet).

A specific time offset can be associated with a particular fragment identifier. For example, a fifteen-minute offset can indicate fifteen minutes after the beginning of a second content item, and the fifteen minute offset can be associated with a particular fragment identifier. When a fragment identifier is received, a corresponding location in the respective second content item can thus be identified. The plurality of second content items and metadata associated with the plurality of second content items can be deposited in the second content provider 202 and transmitted to the second device 206 via the second communication link 204.

In an aspect, the communication element 212 can be configured for receiving and tuning any type of content (e.g., audio content). For example, the communication element 212 can receive audio content (e.g., internet protocol packets, Ethernet frames) from the second content provider 202. In another aspect, the communication element 212 can receive data (e.g., fragment identifiers) related to the first content item from the first device 205. In another aspect, the communication element 212 can be used for fine tuning the second content item provided to and/or rendered at the second device 206 to synchronize with the first content item provided and/or rendered at the first device 205. For example, a user of the second device 206 can adjust the second content item by pressing up and down buttons on the communication element 212 to fine tune the synchronization of a first content item and a second content item.

In one aspect, the first device 205 can be configured to broadcast (e.g., multicast) a current playing fragment or current frame of video over the third communication link 207. The second device 206 can tune to the broadcast to determine the video frame that is being played on the first device 205. Latency in the third communication link 207 can be negligible or can be accounted for a predefined parameter. In another aspect, the second device 206 can register with the first device 205 and receive information about current playing fragment or current frame. A network time protocol can be used to synchronize the clocks on the first device 205 and the second device 206.

In an aspect, the second device 206 can comprise a synchronization element 213. For example, a first content item can be provided and/or rendered at the first device 205, and a second content item can be provided and/or rendered at the second device 206. The synchronization element 213 can receive at least one fragment identifier associated with the first content item from the first device 205. In an aspect, the synchronization element 213 can be configured to process the at least one fragment identifier received. For example, synchronization element 213 can identify a location (e.g., a point) that corresponds to the received at least one fragment identifier based on metadata associated with the second content item. For example, the synchronization element 213 can access metadata of the second content item for a time index associated with the received fragment identifier. For example, a time index can comprise a time offset from the beginning of the second content item. Accordingly, the second content item can be provided and/or rendered at the identified location (e.g., point) in the second device 206.

In an aspect, the first device 205 and the second device 206 can be associated with respective user identifiers and/or device identifiers 209. As an example, the device identifier 209 can be any identifier, token, character, string, and/or the like, for differentiating one user or user device from another user or user device. In a further aspect, the device identifier 209 can identify a user or user device as belonging to a particular class of users or user devices. As a further example, the device identifier 209 can comprise information relating to a device (e.g., the first device 205, the second device 206), such as a manufacturer, a model or type of device, a service provider (e.g., content service provider), a state associated with respective device, a state of the a device, a locator, and/or a label or classifier. Other information can be represented by the device identifier 209. In an aspect, the device identifier 209 can be included in the communication between the first device 205 and second device 206, between the first content provider 201 and the first device 205, between the second content provider 202 and the second device 206. For example, the device identifier 209 can be received by the second content provider 202 as part of a request for a second content item (e.g., an audio content item). Upon receiving the request for a second content item, the second content provider 202 can transmit the requested second content item to the second device 206 according to the device identifier 209.

In an aspect, the device identifier 209 can comprise an address element 210 and a service element 211. In an aspect, the address element 210 can comprise or provide an internet protocol address, a network address, a media access control (MAC) address, an Internet address, or the like. As an example, the address element 210 can be relied on to establish a communication session between the first device 205 and the second device 206 or other devices and/or networks. As a further example, the address element 210 can be used as an identifier or locator of a device (e.g., the first device 205, the second device 206). In an aspect, the address element 210 can be persistent for a particular network. In an aspect, the address element 210 can be included in the communication between the first device 205 and second device 206, between the first content provider 201 and the first device 205, between the second content provider 202 and the second device 206. For example, the address element 210 can be received by the second content provider 202 as part of the request for a second content item (e.g., an audio content item) from the second device 206. Upon receiving the request for a second content item, the second content provider 202 can transmit the requested second content item to the second device 206 according to the address element 210.

In an aspect, the service element 211 can comprise an identification of a service provider associated with a device (e.g., first device 205, second device 206) and/or with the class of a device (e.g., first device 205, second device 206). The class of a device can be related to a type of device, capability of device, type of service being provided, and/or a level of service (e.g., business class, service tier, service package, etc.). As an example, the service element 211 can comprise information relating to or provided by a communication service provider (e.g., content service provider) that is providing or enabling data flow such as communication services to a device. As a further example, the service element 211 can comprise information relating to a preferred service provider for one or more particular services relating to a device. In an aspect, the address element 210 can be used to identify or retrieve data from the service element 211, or vise versa.

In an aspect, a first content item provided and/or rendered at the first device 205 can be segmented into transport packets of a predetermined size. As an example, each transport packet can comprise a fragment identifier. A fragment identifier can comprise a code, a piece of text, a message, a label, a pattern, an annotation, a marker (e.g., watermark), an index, and/or the like. In an aspect, a fragment identifier can function as a time stamp, indicating a time point (e.g., starting point, ending point), and a time interval of a respective transport packet. A time stamp can be accurate to within seconds or shorter. As another example, a fragment identifier can be a watermark that is imperceptible to human detection. For example, a watermark can be a specific frequency or a combination of a plurality of specific frequencies beyond human hearing (e.g., 20 kHz-22 kHz).

In one aspect, a second content item can be ingested from the first content item and provided and/or rendered at the second device 206. In one aspect, the second content item can be synchronized with the first content item at the second device 206. For example, the first device 205 can broadcast at least one fragment identifier of the first content item to the second device 206 via the third communication link 207. In an aspect, the second device 206 (e.g., synchronization element 213) can be configured to process the received at least one fragment identifier, and identify a location (e.g., point) in the second content item that corresponds to the at least one fragment identifier. As such, the second content item can be provided and/or rendered at the second device 206 at the identified location (e.g., point). The first content item provided and/or rendered at the first device 205 and the second content item provided and/or rendered at the second device 206 can be synchronized.

In another aspect, the second content item can be synchronized with the first content item at the second content provider 202. For example, the second device 206 can transmit a request for one of a plurality of second content items to the second content provider 202. The second content provider 202 can communicate with the first content provider 201 to receive at least one fragment identifier associated with the first content item being provided and/or rendered at the first device 205. Upon receiving the at least one fragment identifier, the second content provider 202 can select the requested second content item (e.g., audio content item), and identify a location (e.g., point) in the requested second content item that corresponds to the received at least one fragment identifier. For example, the second content provider 202 can access metadata of the requested second content item for a time index associated with the received at least one fragment identifier. Accordingly, a location (e.g., a time offset, a time point) in the requested second content item can be identified. The second content provider 202 can provide the second content item at the identified location (e.g., point) to the second device 206.

FIG. 3 is a flowchart illustrating an example method 300. At step 302, a first content item can be received. For example, the first content item can be received at a content provider 201. As an example, the first content item can comprise video content, audio content, text, metadata, application, and/or the like. In an aspect, the first content item can comprise a plurality of fragment identifiers. For example, the first content item can be segmented into transport packets of a predetermined size, and each transport packet can be associated with a fragment identifier. A fragment identifier can comprise a code, a piece of text, a message, a label, an annotation, a pattern, a marker, an index, a signal, and/or the like. In an aspect, a fragment identifier can function as a time stamp, indicating a time point (e.g., starting point, ending point), and a time interval for a specific transport packet. As an example, a fragment identifier can comprise a watermark that is imperceptible to human detection. A watermark can comprise a specific frequency, or a combination of a plurality of specific frequencies in a range beyond human hearing (e.g., 20 kHz-22 kHz).

At step 304, a plurality of second content items can be generated based on the first content item. In an aspect, a plurality of second content items can be ingested from the first content item. The plurality of second content items can comprise a plurality of audio content items associated with the first content item. Examples of second content items can comprise audio files generated for hearing aids (e.g., loudness), language training (e.g., English, French, Spanish), parental control (e.g., certain words removed), narration (e.g. for blind people), director's commentary, music only versions, parody dialogs, minors' versions (e.g., no music or effect), 3-D audio (e.g. object based audio), and content formats (e.g., MP3, AAC, MID, AIFF, WAV, MOV, M4A, MP4). The plurality of second content items can be stored at the second content provider 202 and transmitted to the second device 206 via the second communication link 204.

At step 306, metadata associated with the plurality of second content items can be generated. In an aspect, metadata can comprise descriptions of the respective second content items (e.g., audio files), such as hearing aids, language training, parental control, narration, music only versions, minor's versions, 3-D audio, content format, and/or the like. A menu can be created based on the descriptions of the respective audio files. Accordingly, a user of the second device 206 can select a particular second content item from the created menu. In another aspect, the metadata can comprise a time index, and corresponding fragment identifiers associated with the first content item. As an example, the time index can comprise a time offset with respect to the beginning of a second content item. As another example, the time index can comprise a time point (starting point, end point), and a time interval associated with a specific segment of a second content item.

At step 308, the first content item can be transmitted to a first device via a first communication link. For example, first content provider 201 can distribute (e.g., multicast, unicast) the first content item to the first device 205 via a first communication link 203. In an aspect, the first communication link 203 can be a quadrature amplitude modulation (QAM) channel, an internet protocol (IP) channel, or combination thereof. The first communication link can comprise network adapters, switches, routers, modems, servers, bridge, repeaters, communication gateways, a session border controllers, boundary devices, CPE, headends, CMTS, and the like, connected through wireless links and/or physical links. As an example, the first device 205 can comprise a set top box, a television, a network device, a computer, a tablet, a personal data assistant, a smart phone, and the like.

At step 310, at least one of the plurality of second content items and the metadata associated with the at least one of the plurality of second content items can be transmitted to a second device via a second communication link. For example, a user of the second device 206 can select a particular second content item from a menu created according to the metadata of the plurality of second content items. In an aspect, the second communication link can be an internet protocol (IP) channel. For example, the second communication link 204 can be an out of band (OOB) channel of the first communication link 203. The second communication link can comprise network adapters, switches, routers, modems, servers, bridge, repeaters, communication gateways, a session border controllers, boundary devices, CPE, headends, CMTS, and the like, connected through wireless links and/or physical links. As an example, the second device 206 can comprise a set top box, a television, a network device, a computer, a tablet, a personal data assistant, a smart phone, and the like.

At step 312, the first content item and the at least one of the plurality of second content items can be synchronized based on at least one fragment identifier of the first content item, and the respective metadata associated with the one of the plurality of second content items. For example, the second content provider 202 can receive a fragment identifier associated with the first content from the first content provider 201. The second content provider 202 can access the metadata of the second content item to identify a corresponding location (e.g., point) in the second content item being provided and/or rendered at the second device 206. As an example, the metadata can comprise a time index and corresponding fragment identifiers associated with the first content item. For example, the location (e.g., point) can be identified as a time offset (e.g., 15 minutes 9 seconds) with respect to the beginning of the second content item. The second content item can be provided and/or rendered at the second device 206 at the identified location (e.g., point, time offset). Thus, the second content item can be synchronized with the first content item.

FIG. 4 is a flowchart illustrating another example method 400. At step 402, at least one of the plurality of fragment identifiers can be received. In an aspect, the at least one of the plurality of fragment identifiers can be associated with a first content item. In an aspect, the first content item can be transmitted to the first device 205 via a first communication link. As an example, the first content item can comprise a video content, audio content, metadata, application, text, and the like. As another example, the first device 205 can comprise a set top box, a television, a network device, a computer, a tablet, a personal data assistant, a smart phone, and the like. In an aspect, the first device 205 can broadcast at least one of the plurality of fragment identifiers to the second device 206 via the third communication link 207. In another aspect, the second device 206 (e.g., the synchronization element 213) can access (e.g., detect, process, decode) at least one of the plurality of fragment identifiers (e.g., watermarks) of the first content item. For example, the second device 206 can access at least one of the plurality of fragment identifiers by reading the header of at least one corresponding fragment. In a scenario that the first device 205 and the second device 206 are a single device, at least one of the plurality of fragment identifiers can be received without using the third communication link 207.

At step 404, a second content item can be received via a second communication link. For example, the second content item can be transmitted from the second content provider 202 to the second device 206 via the second communication link 204. The second content item can be associated with a first content item. As an example, the second device 206 can comprise a set top box, a television, a network device, a computer, a tablet, a personal data assistant, a smart phone, and the like. In an aspect, the first device 205 and the second device 206 can be a single device. The second content item can be ingested from the first content item. The second content item can comprise audio content, text, metadata, application, and the like. In an aspect, the first content item can be associated with a plurality of fragment identifiers.

In an aspect, the second content item can be associated with metadata. In an aspect, metadata can comprise descriptions of the respective second content items (e.g., audio files) for diverse purposes, such as hearing aids, language training, parental control, narration, music-only versions, minor's versions, 3-D audio, content formats, and/or the like. A menu can be created based on the descriptions of the respective audio files. Accordingly, a user of the second device 206 can select a particular second content item from the menu. In another aspect, metadata can comprise a time index and corresponding fragment identifiers associated with the first content item. As an example, the time index can comprise a time offset with respect to the beginning of a second content item. As another example, the time index can comprise a time point (e.g., starting point, end point), and a time interval associated with a specific segment of a second content item.

At step 406, a location in the second content item corresponding to the received at least one of the plurality of fragment identifiers can be identified based on the metadata. For example, the second device 206 (e.g., the synchronization element 213) can process the at least one of the plurality of fragment identifiers received from the first device 205, and identify a corresponding location (e.g., point) in the second content item. For example, upon receiving the at least one fragment identifier, the second device 206 (e.g., synchronization element 213) can access the metadata of the second content item to identify a location (e.g., point) that corresponds to the received at least one of the plurality of fragment identifiers. For example, the metadata can comprise a time index and corresponding fragment identifiers associated with the first content item. The location can be identified as a time offset (e.g., 15 minutes 9 seconds) with respect to the beginning of the second content item or a specific segment of audio content item.

At step 408, the second content item can be provided and/or rendered at the identified location in the second content item. The second content item can be played on the second device 206 at the identified location (e.g., point) to synchronize the first content item being provided and/or rendered at the first device 205. In an aspect, a user can adjust the second content item on the second device 206, for example, by pressing up and down buttons on the communication element 212 to achieve the fine tuning of the synchronization of the first content item and the second content item.

FIG. 5 is a flowchart illustrating an example method for providing content. At step 502, a request for an audio content item can be received. In an aspect, the second content provider 202 can receive a request for an audio content item from the second device 206. The audio content item can be associated with a video content item transmitted to a first device 205. As an example, the first device 205 can comprise a set top box, a television, a network device, a computer, a tablet, a personal data assistant, a smart phone, and the like. As an example, the second device 206 can comprise a set top box, a television, a network device, a computer, a tablet, a personal data assistant, a smart phone, and the like. In an aspect, the first device 205 and the second device 206 can be a single device.

In an aspect, a user of the second device 206 can request a specific audio content item from a plurality of audio content items from a menu. An audio content item can be requested for diverse purposes, such as hearing aids (e.g., loudness), language training (e.g., English, French, Spanish), parental control (e.g., certain words removed), narration (e.g. for blind people), director's commentary, music-only versions, parody dialogs, minors' versions (e.g., no music or effect), 3-D audio (e.g. object based audio), audio content format (e.g., MP3, AAC, MID, AIFF, WAV, MOV, M4A, MP4) and/or the like.

At step 504, a fragment identifier associated with a video content item being transmitted can be determined. In an aspect, the second content provider 202 can communicate with the first content provider 201 to receive a fragment identifier associated with the video content item being transmitted to the first device 205. For example, the first content provider 201 can transmit the fragment identifier to the second content provider 202 via wired and/or wireless communication protocols. As another example, the second content provider 202 can access (e.g., detect, process, decode) the fragment identifier (e.g., watermark).

At step 506, a location in the audio content item corresponding to the fragment identifier of the video content item can be identified. The audio content item and a location (e.g., point) in the audio content item can be identified at the second content provider 202 based on metadata associated with the requested audio content item. In an aspect, the metadata can comprise descriptions of the respective audio files. In another aspect, metadata can comprise a time index and corresponding fragment identifiers. As an example, the time index can indicate a time offset with respect to the beginning of the respective second content item. For example, a fifteen-minute offset can indicate fifteen minutes after the beginning of a second content item, and the fifteen minute offset can be associated with a particular fragment identifier. When a fragment identifier is received, a corresponding location (e.g., point) in the audio content item can thus be identified. For example, the location can be identified in terms of a time offset (e.g., 15 minutes 9 seconds) with respect to the beginning of the audio content or a specific segment of audio content item.

At step 508, the audio content item can be transmitted at the identified location (e.g., time point) in the audio content item. As such, the audio content item being provided and/or rendered at the second device 206 can be synchronized with the video content item being provided and/or rendered at the first device 205. In an aspect, a user of the second device 206 can adjust the second content item, for example, by pressing up and down buttons on the communication element 212 to achieve the fine tuning of the synchronization of the video content item and the audio content item.

In an exemplary aspect, the methods and systems can be implemented on a computer 601 as illustrated in FIG. 6 and described below.
